If the roof of the vehicle is sloped such that the heat
pump cannot be mounted within the maximum
allowable degree deviations, an exterior leveling
shim will need to be added to make the unit level.
A typical front to back leveling shim is shown in
Figure 3.
FIGURE 3
Once the heat pump has been leveled, some
additional shimming may be required above the
interior ceiling assembly. The heat pump and
the interior ceiling assembly must have a squared
installation relationship before they are secured
together.
D.
After the mounting hole is properly prepared, remove
the carton and shipping pads from around the heat
pump.
Carefully
lift the unit to the top of the
vehicle. Do not use the outer plastic shroud for
lifting. Place the heat pump over the prepared
mounting hole. The pointed end (nose) of the shroud
must face towards the front of the vehicle. Pull down
all loose electrical connectors from the heat pump
through the mounting opening and let hang.
V. SECURING THE HEAT PUMP TO THE ROOF
See Figure 4
A mounting frame is supplied with the ceiling assembly.
Follow the steps below to secure the heat pump to the roof.
A.
Locate the heat pump mount gasket over the
356mm to 381mm square opening in the roof.
B.
Install the ceiling assembly mount frame using the
four bolts, washers and springs found with the
ceiling assembly.
C.
Proper tension has been achieved for each bolt when
the spring coils have just come together (See
Figure 4). The upper unit has now been properly
installed with optimum gasket compression.
D.
If the heat pump is equipped with an optional
evaporator condensate pump, a 13 mm I.D. hose
must be provided that runs from the 357 mm square
opening, through the vehicle ceiling and down the
side wall to allow water to drain under the vehicle.
The hose must not be allowed to kink shut while
making a bend. Connect the top end of the drain
hose to the barbed fitting shown in Figure 4.
